{I AMES i. BYERS, 'oIiciILFPon'n MISSISSIPPL Assioma or ons-THIRD To WILLIAM h ,ANDREW DAVIS AND oNE-'IIIIRIII fro FLETCHER LLwILLIAIfI BEALnor GULFPoRnf l the United safes of America', residing ai Gulfport, in. f. the county of Harrison and siste of Mississippi, have 11.5" invented new and lusrefu] Improvements in Wood Saturatingvand CoatingApparatus, oi the iol'-l lowing is aspecication. j K

invention relates to wood, saturating and coating apparatus, and Vparticularly to an apparatus ior 41() impregnatingand coating shingles and wooden strips or4 articleswith a preservative liquid in such a manner as to I.fill thepores to preserve the wood to a. maximum degree, as well as to a durable, iinish to A f there-into.v A shaft'l extends vertically tifhin the the surface of the wood. i N

The object of' the invention isto provide an apparatus of this character, whereby the wood to be treated any be preliminarily subjected to the action of steain to open its pores and relieve it from thesap and acids contained therein, and then treated with the preservative liquid to force it therein under pressure so as to close the-pores and cover the surface.

The accompanying drawing shows partly in eleva'- tion and partly in central vertical sectionv a wood satu- .l rating apparatus constructed in accordance with my invention. i In the drawing-the numeral 1 designates a receiverv or chamber to contain the shingles or other wooden l articles to be treated, said receiver being of rectangular or any other suitable form and composed ofsorne; y suitable material which will be air-tight and notaiected to an appreciable extent by the action of steam.`

, In the present instance I haveshown said receiver in the form-of `a rectangular metallic box having at one side an inlet opening for the introduction' and `re-A moval of the goods, said opening being closed byan approved type of door 2. The receiver is further provided adjacent to itsupper end` with a test valve or cock 3 adapted to'be opened to permity of the exhaust of airtherefrom when steam is admitted `theie'into to- 50 ablyfastened thereto in any preferred manner. This I enable the operator to determine` when the receiver is y lcompletely filled with steam.` steam supply pipe 4 leading from a boiler or other source of 'steam supply extends above the receiver andvisr connected to the upper end thereof through the medium of a pipe `E:

i '45. containing a valveffwhereby the supply of steam to the receiver may be regulated. Arranged at any suitable point adjacent tothe receiver is a reservoir? for the preservative liquid,- comprising a cylinder closed at its upper and lower ,ends by heads 8 and 9 detachreservoir is provided with'an ordinary type of gage 10, whereby the level oi. the paint contained therein lmay I be determined at anytime. Arranged within thereservoir'is a coil 11 communicating at its upper end by 55 a pipe 12 extending through a plug'or box1 3 i'speincstioiigfnstters Intera'.V

shaft extends through the coil and carries a series of stirrer blades`20 arranged to lrotate within the coil,

" tion of thesteam in the coil maybe drawn off'when' 'steanr supply ppefi at a point adjacent tn the valve- -fronithe pipe 25 to the bottom' of the receiver 1 is a pipe 28 vwhich extends at an upward angle of inclinapass pipe 30 bridgesacross the valve 29, and has its woon sarcasme ycousins APrnA'rUs.

in the 8 with 'the adjacent end of the ste am suppipe 4, avalve 14 beingl disposed between thev `juxtaposed yends of saidy pipestc lregulate thesupply ofstea'mli'to the coil. The impregnating and coating liquid employed maybe composed oi any desired preservative oil, such as pine oil, mixed or not with any desired pigment, and is introducedinto the receiverf'tlirough a lling opening inthe head 8, which opening is normallyclosed by a' cap 15. .The liquidis kept Yheated toa desired degree of temperature to o5 i prevent yit irombeing supplied at too low a degree of temperature to the receiver l. by the heat'radiated v i i from the coil 1l emanating from the steam introduced reservoir and is journaled'in bearings 17 andy 1S earrieijby the nppix 4and lower heads and extends through the bearing 1S and is provided with an actu-Y ating crank handle 19.` The inclosed portion of the whereby the liquid may be readily and conveniently agitated to insure.,- a `thorough admixture of its ingredients prior'to its passage into the receiver 1 for use..

The lower end of;the coil isconnected with a bypass or auxiliary steam supplypipe 21 which extends through a plug or stutlng box 22 in the bottom head vi), and is provided adjacent thereto with a'valve 23 -throughwhich the water-'resulting from the condensa- ,ever required. Th'e said pipe 21 connects with the 1'4 and is providedbetween said supply pipe and the valve 23 with' a valve .24, whereby the supply of i steam to the coil therethroughfruay be controlled.

A dir-charge pipe 25 leads from the bottom of the receiver andconnects with a drain pipe 26, whereby the vcontents of the reservoir may be drawnv ofi rwhenever desired. A valve 27 is interposed' between ythese pipes to.cut ofi connection between them.' Leading tion between said pipe 25 andthe receiver and is pro-- vided with an intermediatecut-'ol valve 29.` A byterr'ninals connected with the pipe 28 o`n` opposite sides 10 of said valve and provided with check valves 3 1 and 32. Arranged in the pipe 30 between the check valves is i a pump cylinder133 communicating at itsflower ends' with theportions of thepipe 30 and having operatively 129 are closed to cut 'of'communicationbetween the reservoir, drain pipe and receiver," and the valve 6 is rstsntesvruiaisov.
